METHOD OF FASTENING CUSHION-TIRES T0 RIMS;

Original application filed May 21, 1920, Serial No. 383,277. Divided 23,1920. serialnaaoazsa new and useful Improvements in Methods of Fastening Cushion-Tires to Rims, of which the following is a specification.

My invention relates to certain new and useful improvements in themanufacture of cushion tiresJ In manufacturing cushion tires it is the practice to build up the, tire on a rim so thatthe tire and rim may be substituted on wheels now employing pneumatic tires without the necessity of changing the construction of the felly band or the rim fastening devices;

In building up the tiresxon the rim diiliinsecuring the tire'so tightly to the rim that it will not slip 'annula'rly under tractive force. It is to overcome this tendency of the tire to slip or creep on the rim that I have devised the method constituting the subject matter of this application. In carrying out my invention, I lay or build tire on the rim in the usual manner but before building up the superstructure of the tire I rivet the base structure to the rim at intervals and tie the base structure in place I by annular wires wound around the same around the rivets, after which the su aerstructure of thetire is built up and the entire mass vulcanized in the usual way. thus embedding the rivets and tie wires in the tire structure. I

In the drawing, in which like numerals and letters of reference indicate like parts in all of the figures, the rim consists of the annular. body portions 11 and the central depressed portion 2, the latter being of a lesser radius than that of the body portions 1"1 and adapted to conform closely tothe Specification oi Letters I'atent.

What I claim is: 1. The method of fastening cushion tires to rims which consists in building the base portion of the tire on the rim, fastening the base to the rim at intervals and tying the base by encircling members to the fastening means. I j i 2'. The method of fastening cushion tires to rims which consists in first riveting the base portions of the tire tothe rim, tying the base portions by encircling wires to the rivets and subsequentlybuilding the superstructure of the heads and tie wires therein.
